Vision Zero is the New York City policy, begun in 2014, that treats traffic deaths as preventable rather than accidental. Its most visible product is the citywide default speed limit of 25 miles per hour, which applies on any street that is not posted otherwise. School speed zones, work zones and slow zones are lower still. Speed is the single factor that decides whether a struck pedestrian survives, which is why it is the centre of the policy and of the examination.
New York State law requires every driver to exercise due care to avoid hitting a pedestrian or a bicyclist, and to yield to a pedestrian lawfully in a crosswalk. New York City went further: under section 19-190 of the Administrative Code, a driver who fails to yield and strikes a person with the right of way commits a criminal violation, not merely a traffic infraction. Turning across a crosswalk on a green light is the most common way a professional driver runs into this rule.
State law forbids holding a mobile telephone while driving, and the TLC goes further by forbidding a licensed driver from using a telephone at all while the vehicle is in motion, hands-free included. The only lawful place to take a call is stopped, out of traffic. Fatigue is regulated too: TLC rules cap the number of hours a driver may drive within a 24-hour period and within a seven-day period, and the cap is measured, not estimated.
Keep at least three seconds of following distance and more in rain, snow or fog. Set your mirrors so that the blind spot is as small as it can be, then still turn your head before changing lanes. Scan far ahead rather than at the vehicle in front. Open your door with the far hand so that your body turns and you see cyclists coming. Slow before a curve, not in it. Alcohol, medication and drugs are treated strictly: a driver carrying passengers for hire is judged against the commercial standard, and the TLC requires annual drug testing.

The policy began in 2014 and reshaped speed limits, street design and enforcement across the city. Source: New York City Vision Zero action plan.
2. What is the default speed limit on a New York City street with no posted limit?
The default was lowered as the central measure of the city's street safety policy. Source: New York City Administrative Code, speed limits.
3. What does a posted speed limit lower than the citywide default mean?
Individual streets are posted lower where the city has judged the risk to be higher. Source: New York City Administrative Code, speed limits.
4. Why does the city treat speed as the central safety issue?
The chance of surviving being struck falls very sharply as impact speed rises. Source: New York City Vision Zero action plan.
5. Who is most at risk on New York City streets?
Pedestrians make up the largest share of the city's traffic deaths year after year. Source: New York City Vision Zero action plan.
6. What is a slow zone in New York City?
Slow zones combine a lower limit with physical changes to the street itself. Source: New York City Department of Transportation.
7. What is a school speed zone?
The cameras operate on the days and at the hours posted on the signs. Source: New York City Department of Transportation.
8. How does a speed camera summons reach a driver?
Camera summonses follow the plate, so a leased vehicle produces a conversation with the owner. Source: New York City Department of Transportation.
9. Why should a licensed driver care about camera summonses even when the owner pays?
Owners keep track of which drivers collect them and the Commission has its own programmes for repeat behaviour. Source: 35 RCNY Chapter 80, Persistent Violator Program.
10. What happens to stopping distance as speed rises?
Braking distance rises with the square of the speed, which is why small increases matter so much. Source: New York State driver education materials.
11. What are the two parts of total stopping distance?
The vehicle keeps travelling at full speed throughout the reaction part, before the brakes do anything. Source: New York State driver education materials.
12. What increases reaction distance?
Everything that slows the driver's response lengthens the distance travelled before braking begins. Source: New York State driver education materials.
13. Why is a wet road so much more dangerous than a dry one?
The first minutes of rain are the worst, when water lifts oil off the road surface. Source: New York State driver education materials.
14. What is the sensible following distance in good conditions?
Counting seconds works at every speed, while counting car lengths does not. Source: New York State driver education materials.
15. How should following distance change in rain or snow?
Grip falls first and visibility falls with it, so the extra distance does two jobs at once. Source: New York State driver education materials.
16. How should a driver measure a three second gap?
A fixed object and a count is the only method that works at any speed. Source: New York State driver education materials.
17. What is tailgating?
It removes the reaction distance entirely and turns any sudden stop into a collision. Source: New York State driver education materials.
18. Who has right of way at an unsignalled crosswalk?
State law requires a driver to yield to a pedestrian lawfully within a crosswalk. Source: New York State Vehicle and Traffic Law section 1151.
19. What does the city's Right of Way Law add to the state rule?
The city took the failure to yield out of the traffic ticket category and into the criminal one. Source: New York City Administrative Code section 19-190.
20. When a driver turns across a crosswalk on a green light, who has priority?
A green light permits the turn but does not remove the duty to yield to people already crossing. Source: New York State Vehicle and Traffic Law section 1151.
21. Which manoeuvre most often produces a collision with a pedestrian in this city?
The turning driver is looking for a gap in traffic while people are already crossing beside him. Source: New York City Vision Zero materials.
22. What duty does state law place on every driver towards pedestrians and cyclists?
The duty of due care applies everywhere, not only at marked crossings. Source: New York State Vehicle and Traffic Law section 1146.
23. What should a driver do when a pedestrian steps into the road away from a crossing?
The duty of care does not disappear because the pedestrian is in the wrong. Source: New York State Vehicle and Traffic Law section 1146.
24. A pedestrian crosses against the signal. What is the driver's position?
A collision remains a collision, and the driver is judged on what he did to avoid it. Source: New York State Vehicle and Traffic Law section 1146.
25. What is a leading pedestrian interval at a signalled junction?
The head start puts people into the crosswalk where turning drivers can see them. Source: New York City Department of Transportation street design.
26. Who has right of way when a driver is leaving a driveway across a pavement?
Crossing a pavement means yielding to everybody already walking on it. Source: New York State Vehicle and Traffic Law, entering a roadway.
27. What must a driver do at a stop sign?
A rolling stop is a violation and is also how drivers fail to see people already crossing. Source: New York State Vehicle and Traffic Law, stop signs.
28. What must a driver do at a yield sign?
Yielding means giving way, which sometimes requires stopping and sometimes does not. Source: New York State Vehicle and Traffic Law, yield signs.
29. Two vehicles arrive at an unmarked four-way junction at the same moment. Who goes first?
The rule exists so that neither driver has to guess what the other will do. Source: New York State Vehicle and Traffic Law, right of way at intersections.
30. Who has right of way when a driver is turning left across oncoming traffic?
The turn is completed only when the way is clear in both respects. Source: New York State Vehicle and Traffic Law, turning movements.
31. What is the rule about turning right on a red light in New York City?
The city is the exception to the general state rule, and visiting drivers are caught by it constantly. Source: New York City Traffic Rules.
32. What does a steady yellow signal mean?
Accelerating on yellow is what produces the collisions the phase exists to prevent. Source: New York State Vehicle and Traffic Law, traffic signals.
33. What does a flashing red signal mean?
A flashing red is a stop sign, and a flashing yellow means proceed with caution. Source: New York State Vehicle and Traffic Law, traffic signals.
34. What should a driver do when the signals at a junction are out of order?
Treating a dark signal as a stop is what stops two drivers assuming the same priority. Source: New York State Vehicle and Traffic Law, traffic signals.
